Question

Divide P. 80.00 people so that the second will have twice as much as the first and the third will have P. 5.00 less than the second. how much the first, second and third person gets​?

Answer 1

first collects 17, second 34 and third 29

Explanation:

Total amount to be shared = 80.00

If first person received x

second received y

Third received z

If the second will have twice as much as the first, then;

y = 2x

x = y/2

If the third will have P. 5.00 less than the second, then

z = y-5

y = z+5

Substitute both equation in original equation

x+y+z = 80

y/2 + y + y-5 = 80

y + 2y + 2y -10 = 160

5y = 160+10

5y = 170

y = 170/5

y = 34

x = y/2

x = 34/2

x = 17

z = y - 5

z = 34-5

z = 29

Hence the first collects 17, second 34 and third 29
